To give an example of making an easy, customizable solution … if you did
this in your FO:
<?xep-gradient radial-gradient(circle 100% at center, yellow, darkorange)?>
<fo:block-container width="3in" height="1in" background-color="red">
<fo:block line-height="1in" text-align="center"
font-size="24pt">Gradient</fo:block>
</fo:block-container>
You would have this in XEPOUT:
<?xep-gradient radial-gradient(circle 100% at center, yellow, darkorange)?>
<xep:rgb-color red="1.0" green="0.0" blue="0.0"/>
<xep:rectangle x-from="72000" y-from="208800" x-till="288000"
y-till="280800"/>
You could then customize the solution I provided to read the PI
(xep-gradient, extracting gradient type and color from the XEPOUT and
process.
And if we re-wrote as 2.0, we could just use serialize() function to likely
get the result we need and not build it from strings.

Note that I have used similar solution to do things like rounded corners or
gradient text which is really cool – as in given a marketing document’s
title, applying a gradient to the text.

As promised and I didn’t even wait for the weekend.
Below is a simple example that could be expanded through PIs or Pinpoints or
other ways to carry the information you want for the gradient.
Right now it has fixed colors and is a linear gradient but you could easily
extend this.
I will probably do a new CoolTool and do just that.
What this does – it leverages the XEPOUT format to grab all red rectangles
(an area where you want the gradient --- you could use any color and trigger
on it).
It takes those red rectangles and uses their exact dimensions and replaces
them with a linear gradient SVG rectangle.
NOTE: All things with background colors could be done as they yield a
rectangle – could be a table-cell or block or block-container.
I just used block-containers in this sample.
Now, you could certainly expand all this … use a pinpoint or a PI to carry
the actual colors and type of gradient.
Or params in the XSL if you like.
Gradient-background.fo can be formatted to XEPOUT.
You would see this:
<xep:rgb-color red="1.0" green="0.0" blue="0.0"/>
<xep:rectangle x-from="72000" y-from="376800" x-till="360000"
y-till="520800"/>
A red rectangle.
That XEPOUT can be transformed with the attached identity-gradient.xsl XSL
to make a new XEPOUT.
That XEPOUT now has this:
<xep:image src="data:image/svg+xml;utf-8,<svg
xmlns="http://www.w3.org/2000/svg" width="2in"
height="2in">
 <defs>

<linearGradient id="myLinearGradient1">

<stop offset="0" stop-color="#11908d"
stop-opacity="1"/>
 <stop
offset="1" stop-color="#646452"
stop-opacity="1"/>

</linearGradient>
 </defs>

<rect width="
 2in" height="2in"
fill="url(#myLinearGradient1)"/>

</svg>
 " base="file:/C:Temp"
type="image/svg+xml" x-from="72000" y-from="532800" scale-x="1.0"
scale-y="1.0" width="144000" height="144000"/>
Which changes the rectangle to a UTF-8 encoded inline SVG image.
NOTE – if you use XSL 2.0 you could likely do this easier than I did in the
XSL, feel free to improve!
The result:
Problem solved. No custom development required. A simple solution in a
toolchain.

We are looking at the solution within the context of our development path
and demand.
If there is other folks on this list that would like to see such a feature,
please let us know.
In the meantime, I believe this could be solved through XEPOUT manipulation.
I did a similar solution for background behind rx:flow-section.
I will need to examine and get back to you after the weekend.

Subject: [xep-support] Feature request: "gradient background color"
Dear XEP-Support team,
currently I am looking for a solution to specify gradient background images
to <fo:block> areas.
At antennahouse’s webpages I found this:
<https://www.antennahouse.com/antenna1/wp-content/uploads/2018/02/background
-image-gradient-1.pdf>
https://www.antennahouse.com/antenna1/wp-content/uploads/2018/02/background-
image-gradient-1.pdf
My question:
Can RenderX deliver a comparable functionality as described in that
antennahouse-PDF?
In what time frame can RenderX realize these features and what will be the
prize for this?
I think this would be a nice feature to increase the attractivity of RenderX
products.
Kind regards
Freundliche Grüße
